The COLOMBO Nitrate NO3 Test is used to determine the level of nitrates (NO3) affecting the flora and fauna of a pond.
Nitrates are the waste products of beneficial bacteria that process fish waste in the pond and filtration systems.
Excessive concentration of nitrates can negatively affect the reproduction of fish, as well as provoke the growth of algae,
which begin to dominate aquatic plants, which is undesirable. The absence of nitrates can speak of
a positive balance in the ecosystem of the water body between the amount of waste produced by fish and nutrients
consumed by plants.
The method of application is described in detail on the back of the dough package.
